How to access a custom array created in pre_sim_func_nb after the backtest is complete?

[0xazuki7]

Hi, I created a custom array in pre_sim_func_nb in which I store booleans at each iteration. Question - Is there a way to access the array after the simulation is complete ? I have read about Custom Metrics but it doesn't look to fit my need.

def some_callback(c, my_array, ...):
my_array[i, col] = ...

my_array = np.full(...)
pf = vbt.Portfolio.from_signals(..., some_callback=some_callback, some_args=(my_array, ...))
print(my_array)

Thanks, much appreciated.
